Struggle w/ Give a Background Color to a div Element

Tell us what’s happening:
I don’t understand why it keeps telling me " Define a class named silver-background within the style element and assign the value of silver to the background-color property." Although I think I dit it…

Your code so far

<link href="" rel="stylesheet" type="text/css">
  .red-text {
    color: red;

  h2 {
    font-family: Lobster, monospace;

  p {
    font-size: 16px;
    font-family: monospace;

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
    border-radius: 50%;

  .smaller-image {
    width: 100px;

  .silver-background {
    background-color : silver;


<h2 class="red-text">CatPhotoApp</h2>
  <p class="red-text">Click here to view more <a href="#">cat photos</a>.</p>
  <a href="#"><img class="smaller-image thick-green-border" src="" alt="A cute orange cat lying on its back."></a>
  <div class="silver-background">
    <p>Things cats love:</p>
      <li>cat nip</li>
      <li>laser pointers</li>
    <p>Top 3 things cats hate:</p>
      <li>flea treatment</li>
      <li>other cats</li>
  <form action="/submit-cat-photo">
    <label><input type="radio" name="indoor-outdoor" checked> Indoor</label>
    <label><input type="radio" name="indoor-outdoor"> Outdoor</label><br>
    <label><input type="checkbox" name="personality" checked> Loving</label>
    <label><input type="checkbox" name="personality"> Lazy</label>
    <label><input type="checkbox" name="personality"> Energetic</label><br>
    <input type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>

Link to the challenge:


  .silver-background {
    background-color: silver;

(space removed)

Guys, I am very thankfull to you, had the same “mistake”.
But you know, I did it (put the space between “background-color” and “:”) all the time in previous tasks, and it was OK !!! So now it looks like freaking bug. Pfffff, exhausted me. Thank you again!
